我想得到我CSDN博客的阅读量,那么我应该做一个软件,这个软件可以查看当前的 csdn 博客访问量

界面

启动界面

启动完成输入需要统计的博客的网址

代码

看界面很简单,就一个List做的

主要技术是爬虫

我们先做一个TextBox放博客地址

            <TextBox Margin="10,10,10,10" Header="博客地址" PlaceholderText="http://blog.csdn.net/lindexi_gd" Text="{x:Bind view.PostCsdn.Url,Mode=TwoWay}"></TextBox>

我们还需要类Post存放我们的博客

    public class Post : NotifyProperty
    {
        public Post()
        {

        }

        /// <summary>

                OnPropertyChanged();
            }
            get
            {
                return _linkView;
            }
        }

        public string Original
        {
            set
            {
                _original = value;

            }
        }

        public List<Scrutiny> ScrutinieCollection
        {

        }=new List<Scrutiny>();

            {

            }
            else
            {
                throw new FormatException();
            }

            LinkView = post.LinkView;
            Time = post.Time;

            ScrutinieCollection.Add(new Scrutiny()

获得csdn的访问量积分等,我们需要得到我们现在所在的页,如果我们在第一页就获取,还获取最大页数,如果我们现在不是第一页就不获取

现在我使用的方法是 asp dotnet core 通过图片统计 csdn 用户访问

ListView宽度过小

这个问题简单。

                <ListView.ItemContainerStyle>

                    <Style TargetType="ListViewItem">

                        <Setter Property="HorizontalContentAlignment"

                                Value="Stretch"></Setter>

                    </Style>

                </ListView.ItemContainerStyle>

我们可以使用我们的ListView放数据

获取博客

获取博客可以访问网站,获取源码,使用匹配到的数据

我们写软件,一般是用用一个页面来做导航,这个页面就是一个Frame,然后包含各种导航,所以这个页面会一直存在我们的内存。

然后我们需要把MainPage一开始就导航到我们这个页面,我们可以拿到我们的Content,然后把Content给一个Frame,用Frame导航。


        public MainPage()
        {
            this.InitializeComponent();
            Frame frame=Content as Frame;
            if (frame == null)
            {
                frame=new Frame();
                Content = frame;
            }
            frame.Navigate(typeof(View.AssBjPage));
        }

if (frame == null)一定会true,因为Content 一般是Grid,我们把content改为Frame
